to get back the desired substituted azaarenes. An efficient metal-free visible-light photo-redox catalytic deoxygenation of N-oxides of azaheterocyclic compounds has been developed using acridinium based organo-photocatalyst in blue LED light. High efficiency and mildness of this methodology has been demonstrated through higher deoxygenation yield of wide variety of azaheterocyclic N-oxides with reactive
